在氮气气氛和1100~1300℃温度范围内,对含锌铅粉尘配碳球团中的铅挥发动力学的研究表明:还原温度对铅挥发速率有显著影响,而煤粉粒度及过量碳含量对铅挥发速度则没有影响。求得铅挥发表观活化能为88.74kJ/mol,并确定铅的挥发限制性环节为铅的蒸发和铅通过其表面气相边界层的扩散。
The results of the study on the volatilization kinetics of lead in zinc dust with carbon and lead in the temperature range of 1100 ~ 1300 ℃ show that the reduction temperature has a significant effect on the volatilization rate of lead, while the coal particle size and excess carbon content Lead volatilization rate has no effect. The apparent activation energy of lead volatilization was found to be 88.74 kJ / mol, and lead volatilization and lead diffusion through the surface vapor boundary layer were determined.
